TO ALL WHOM Ill." MAY OONCERN;

Be it known that I, J. D. MILLER, of Enon, in the county ofClark, andState of' Ohio, have invented a new and useful Improvement'inHannes-Fasteners; and I do herebytdeclare the following` to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, in Whichi Figure 1 is a side elevation, showingthe process ofsecuring the fastener. y

Figure 2, a planand elevation of the link.

Figure 3, perspective, showing the hookand other parts secured.

Figures 4 and 5, elevations of hook and sections of link.

, ll/,Iy invention relates to an improvement in haines-fasteners, whichrenders the fastening and unfastening of the same very quickly andeasily done, while there is no danger of its becoming unfastened whilein use. It is also very simple, not liable'to get out of order, and canhe attached to any set of hames with very little trouble. It consistsinthe employment of a hook, of peculiar shape and construction; and, inorder that others may understand the nature of my invention, itsconstruction and operation, I will proceed to particularly describe it.

A A are the hameso'f ordinary construction, and having at the lower endof each a ring, B B. To one of the rings, B, `is attached an ordinarystrap, C, with a buckle, by means of which the fastening may be adjustedto collars of cliii'erentsi'zes.' The hook D is attached to the strap'Cby` means of the link E. p

When the lower ends of the hames are to be secured about the collar, thefree end of the hook D is passed through the ring B, as shown in fig. 1,and, ,beingbrought into position, as shown in iig. 3, the hannes Varesecured. i

- The construction and operation of thelink E and hook D, form'the gistof this invention, and the attachments of those devices will thereforebe passed over without farther comment.

The hook D is -made by forging, casting, or in any convenientmethoch'and has a long and somewhat slender tail or shank, While thepoint lr'eturns Within the bendof the hook, all of which is clearlyshown in iig. 1. The form of the link E is clearly shown inlig. 2.- p

When thefree tend of the hook D is passed` throughf the ring B, as shownin fig. 1', and said end is then carrieddownward and around toward thestrap C, the ring B is caused toslide-along the surface of the hook,

and bc continually d rawn nearer and nearer to the end of the strap C,until the shoulder F is reached, when,

-as the ring passes'into the slight recess behind said shoulder, itrecedes slightlyfrom the eud'of the strap, and

the elasticity of the collarzwll constantly tend to force the ends ofthe hannes asunder, ,and the same elasticity vwill therefore always keepthe-ring in thcrccess behind the shoulder F, until force is applied toreverse -the motion of the hookrsuiheient te overcome the elastic forceof the collar. Iii-'drawing up the hames, the point ofgreatestcompression will be just at theA point of passing over` theshoulder F.'

The link Eis specially designed andproportioned so that, before thestra-p 'C has been put through-it, the said link w'ill just pass overthe returned c'urve of the hook, as shown in tig. 5, while, when thestrap is in place, its* thickness will soniuch rcduce'the capacitymofthe link, Vthat it will not pass over said hook. This is shown in iig.4. This inode ofeonstrueting enables me to` make them entire andcomplete without welding or 'Without diiculty, and by any person.

soldering. l l Itwill appear fromthe above, that the presence of thestrap C suffices-to make the connection of the link and hook permanent,while,`iu case of the breaking of either link or hook, the 'broken partcan be replaced This fastening can be applied to any harness, as thehaines are always provided with rings, B B, and if a strap has beenheretofore used,'it will' only be necessary to shorten it up and attachthe link and lever. Y

The forms of the hook and link may of course be somewhat varied, Withoutin any particularV changing the operation of the parts. I

The shank of the hookD is made flat, andso broad that it cannot passthrough the `narrow part of the link E, though it 'might be passedthrough the broad-part, when the strap should be removed therefrom.`There is no necessity involved in its ahility to pass through the broadpart of the link, as it may be put together in the manner beforedescribed.

Having described my invention, what I claim as new is,- l z 1. 'lhelever D, constructed with the shoulder F, and a recess l'behind-it, inwhich to receive the ring B, when in working position, substantially asdescribed. p Y

2. The hook D, with the point returned within the fold of the hook asdescribed,vin combination witha. llink;

proportioned so that, while naked, it may be passed over the point ofthe hook, but not where the strap C is present, substantially as setforth. f

3. The lever D and crooked link E, constructedsc as to operate in themann-er and for the-purpose described. l
